Coolant, changing
IMPORTANT! To avoid damage to the engine, different kinds
of coolant or corrosion protection must not be mixed with
each other, see page 117.
Change coolant every 6000 hours or every fourth year.
Draining
1 Remove the expansion tank cap (A).
2 Bend down hose (B) by the right side of the radiator and press
in the clamp on the draining nipple so that coolant flows out.
3 Let down the belly plate. Connect the draining hose to the
nipple at the rear on the engine (C).
4 Connect a hose to draining nipple (D) (2 pcs) down on the right
side of the engine.
NOTE! The cooling system does not become safe against
frost even after draining. There may be pockets of water left.
Take care of filters/oils/liquids in an environmentally safe way,
see page 91.
